Sauce Visual is a visual testing tool that provides technical aspects to find the root cause analysis of visual regressions in tests, including Smart Hybrid Diff, which captures both screenshot and DOM snapshot data for comparison. This allows teams to identify the specific changes made to the UI and understand how they occurred, leading to faster time-to-market and more efficient applications with happier customers. By implementing Sauce Visual, teams can reduce false positives, save engineering hours, and improve their testing experience, ultimately achieving a better balance between automated and functional testing.
